ln t 1e position I, the receptacle to receive its iinal charge, while VII and VIII the receptacles are verticallyY in line beneath the position I, so that in passing from position VII to position I, the receptacles move vertically upward in line with the downwardly flowing stream of glass.

The guiding' of the molds to and through e successive positions which they occupy t e rotation ofthe frame 5, and the mainin the desired position through these movements, is effected in the ollowing n'i'auner: V

Each mold is provided above thecenter of gravity with a pair which bear in 'blocks mounted in radial slots il and l2 arms oi' the rotating frame 5. The trunnions 'i' and S are extended on each side of the 'blocks 9 and l() to receive rollers 13 and these rollers engage, during rotation of the frame, with fixed tracks, or wa s, 15,16, 17 and 18, in a mannerclearly shown in the drawings.

The shaft 6, carrying irame `5, is rotated step by step through the intervals separat` ing t position, 81 of a revelution in the 'lorm shown, by means of a pinion 1.9 which engages the gear 20 on the sha it This step-hy-step movement is ci?" ted hy rotating the gear i9 tlnough one complete rotation at the desired intervals hy means of the interrupted is in place in posltions evident,

4 medium of a rack VIH to the charging position opened by this case for severing' the interrupting its flow to the molds while the latter are being moved, consists of two reciprocating blades 23 'and Q4 which are mounted inV ways on the frame 25 and are moved by means of a piston 2G in a cylinder 27.. The piston 26 is directly connected to the blade Q3 by means of rods 28 and it is also connected to the blade 24 through the 29 which engages with a toothed crank disk 30, the latter being coupled to the blade 24. by means of a connecting rod 81. The piston 26 is actuated by means of compressed air or steam which is lead to the cylinder 27 through a pipe 32. This pipe contains a two-way valve'33 which is opened andclosed at the desired intervals by the joint action of a cam 34 and a spring 35.

The operation is as follows :-A mold is maintained in the position I until.' a suiicient quantity of glass has been delivered thereto, or is ready for flowing stream. It will be readily apparent that this quantity may be acquired before the lower end of the stream actually enters the receptacle. The two-way valve 33 is then opened by the action of the cam 34 and the iston 26 is moved outwardly in the cyl# inder 27,' thereby moving the blades 23 and 24C to sever the stream at a point slightly below the orifice in the block. Simultaneously with the severing ofsthe glass, the pin"-y ion 22 is engaged by the toothed segment of" the driving gear 21 and the mold frame 5 set in movement, thus carrying the filled mold from position I toward vposition ll an lifting an empty mold from the 'position l. As soon as the filled mold as moved laterally to one side sufficiently to clear the line of flow ofthe glass, the cutting blades'23 and 24 are the movement of the two-way valve 33 to its exhaust position, thereby relieving the pressure in the cylinder 27 and allowing the parts of the cutting mechanism to be returned to their opened position by means of a spring 36 or some equivalent device. This permits the glass to resume its flow directly downward toward the mold which is rising from positio VHI.

When the molds are in th various successive positions II, Ill, 1V, etc., the glass conl tained therein may be subyected to various forming operations by pressing,

class stream and delivery thereto from the fa plurality low -my hand atPittsburgh, Pennsylvania,

blowing,

etc., and when the molds reach V, they may, if desired, be inverted to discharge the formed articles, or molten glass, may be secured to the trunnions 13 and 1e and arranged to be engaged by fixed racks 38 on the guides 15 and 16.

l claim as my invention:

1. A glass workingl apparatus omprising a rotary member having a horizontal axis and a plurality of receptacles carried by said member and rotatable therewith, and' means for automatically toward and from the axis of the rotary member during rotation of said member and keeping the same upright whereby said members will be caused lo travel in a substantially vertical line during a portion of their orbit.

2. Glass working apparatus comprising a rotary member having a horizontal axis and a plurality of radially extending receptacle guides, a plurality of receptacles slidably mounted one in each guide, and a second guide cooperating with the receptacles to roduce relative radial movementI dur-ing rotation of the carrying member whereby the rece low position and raised therefrom substantially verticall and upright and thereafter shifted lateral y, a pivotal support for each mold, a pinion carried by each mold, and means for engaging said pinion successively to invert the' molds.

3. Glass working apparatus comprising a rotary member .having a horizontal axis and. guides, a plurality of receptac es -slidably mounted one in each guide coperating .with produce relative radial movement rotation of th'e carrying the recep d urin g member. whereby' tially vertically and upright and thereafter d shifted-.laterali 4.
